Community-Acquired Meningitis Complicated by Pyogenic Ventriculitis: A Case Report

Abstract

Ventriculitis is the inflammation of the ependymal lining of the ventricles in the brain which usually occurs as a complication of meningitis, intraventricular devices, intracranial surgery, or brain abscess. Common clinical features include fever, altered mental status, headache, and neck rigidity. Some commonly associated organisms are Streptococcus, gram-negative Bacillus, Staphylococcus, and Meningococcus. Here, we report the case of a 57-year-old female presenting with fever, headache, and altered mental status, along with positive physical examination findings of Kernig's and Brudzinski's signs without any focal neurological deficits. Cerebrospinal fluid analysis findings were consistent with bacterial infection with neutrophilic leukocytosis, high protein, and low glucose. The blood culture was positive for Streptococcus pneumoniae. Magnetic resonance imaging was negative for enhancement of the meninges but showed fluid-filled layering in the ventricles consistent with pyogenic ventriculitis. The patient improved clinically within three days of initiation of empiric antibiotics.
